To all whom it may coooewc:

Be it known that ii Tmioooioc ABTMEYER, a citizen of the United States,and a resident of Wilkinsburg, in the couiity ofiAlleghe'ny members, andthe process of percolation has been carried on solely by difiei ence ofpressures obtaining in the various portions of the epoeifetusu Accordingto my invention, 1 provide e means for aiding pcrcoietion that is odditional to the usual means; The fountain tube is resiliently sud looselysupport-ed within the heater member and adapted for reciprocatingmovement with respect thereto. An upward movement is imported. to thefountain tube bythe expending steam in the heating chamber, enditsdownward or return movement is cushioned by means of o spring; that assciated with said tube and said member. i ew liquid for hestiug isthereby forcibly taken in, and the hosted fluid is sided in its upwei dprojection.

of the well 5. A side opening 11 in one of i said oapsond a side opening12 in the tube 4 serve to admit liquid to the central well .5 where itis heated. It is understood that other suitable means for admittingliquid may be employed. One end of the spring 8- rests upon the upperend 13 of the sleeve 7,' and e, Tingle is fastened to the tube l by ascrew 15 and is provided with e circumferentisl disposed groove 16 inwhich the 11 per end of the spring 8 is disposed. The oregoingconstruction is adopted to permit resilient reciprocetory movement ofthe tube at and valve member 6 upwardly and downwardly in said well. I

Assuming the apparatus to be in the position shown in the drawing, theoperation is as follows: Liquid enters through the space between thesleeve '2' and the valve 6, which space is shown somewhat enlarged forthe sake of indicating that there is a s use between these elements. Theliquid t on passes through the openings 11 and 12 in the cap member 9and the tube 4, respectively, and drops to the bottom of the well 5,where it is heated and fleshed into steam. The steam pressure acts onthevalve member (1 as e piston, forcing" said member upwardly when moreliquid is admitted tlllfiflllg'll the opening 11. As soon as the steampressure has momentarily decreased,

usual attachments-returns the valve member 6 and attached tube 4 totheir origins]. posi tieu, this downwerdniovement being cus ioned by thespring The reciprocetoi'y movement is continued {LS long as heat is f1"nisi'aed, thus aiding the process of posed iou.

do not wish to be restricted to the speciiic details and structureherein set forth, but desire that only such limitations shell beimposed, as sire indicated in the appended claims.

I claim as my invention:

1, lo a percolating element, the combinw tion with on electric heatermember comprising 21 base, of a fountain tube. and

resilient means for supporting the weight in said Well, said valve beingfreely operable during the normal operation c said device to control theflow of liquid into said well.

3. In a percolating element, the combination with an electric heatermember, of a fountain tu'be. associated therewith and reciprocable withrespect thereto during the operation of the device, and resilient meansfor supporting the weight of the said tube.

4;. In a percolating device, the combination with a base having acentral well, of heating means carried by said base, a fountain tubesupported within said well and adapted to move with respect theretoduring the o eration of the device.

5. n a percolating element, the combination with a base having a centralwell, of electric heating means carried by said base, a fountain tubesupported within said well, and resilient means for sup orting theweightof the said tube on sai base.

6.' In a percolating device, the combilation with a heater member havinga central well of less diameter than the said heater member, of afountain tube, and means to."

S0 511 porting said tube upon said member that the tube may reciprocatewith respect to said member during the operation of the device.

inmate 8. A percolating device comprising a base having a liquid well inthe upper side thereoi, electric heating means disposed adjacent saidwell in said base, a fountain tube supported. on said base andcxtcndii'ig into Said well, and a valve secured to the lower end of saidtube and fitting Within said Well, said valve and tube being freelymovable up and down in said well during the normal operation 0t saiddevice to control the flow of liquid into said well.

9. A percolating device comprising a base having a liquid well in theupper side thereof, electric heating means disposed adjacent said wellin said base, a fountain tube sup ported on said base and extending intosaid Well, a valve secured to the lower end of said tube and fittingwithin said well, and means for resiliently supporting said valve andtube upon said base, whereby said valve and tube are freely movable upand down in said well during the normal operation of said device andcontrol the flow of liquid into said well.

10. A percolating device comprising a hol-v low base having a liquidwell in the upper side thereof, electric heating means disposed withinsaid base adjacent said well, a founta-in tube extending into saidgwell, a valve secured to the lower end of said tube and fitting withinsaid Well, and a spring surrounding said tube and mounted upon the upperside of said base, said spring resiliently supporting said valve andtube whereby the same are freely movable up and down in said well duringthe normal operation of
